x/10 + x/4 = 21 /*40
4x + 10x = 840
14x = 840
x = 60 = total number of points the team scored
Answer:
Total number of points in game is 60.
Step-by-step explanation:
Information given in the question:
Let x be the total scored in the game.
Contribution of Brian in the game = [tex]\displaystyle\frac{x}{10}[/tex]
Contribution of Joe in the game = [tex]\displaystyle\frac{x}{4}[/tex]
Total contribution of Brian and Joe in the game = 21
According to the question, the following equation can be used to represent the situation:
[tex]\displaystyle\frac{x}{10} + \displaystyle\frac{x}{4} = 21[/tex]
[tex]\displaystyle\frac{7x}{20} = 21\\\\ 7x = 20\times 21\\x = 60[/tex]
Thus, the total score of the game was 60.
